Traffic Escorts

Traffic Escorts play a critical role in the safe movement of high-risk, Over Size Over Mass (OSOM) vehicles throughout Western Australia.

A Traffic Escort Warden (TEW) is required when the Restricted Access Vehicle (RAV) is in excess of 5.5 metres in width and/or 40 metres in length, unless specified otherwise on the Single Trip Permit or within the Single Trip OSOM Vehicle Standard Operating Conditions.

A Warden will acocmpany the heavy vehicle in a Traffic Escort Vehicle which has red and blue flashing lights on the roof, "Traffic Escort” displayed on both sides of the vehicle, and usually also has a blue and white sign on the roof with the words “Oversize Escort”.

Wardens are responsible for:

  • Preparing a journey management plan
  • Submitting a Green Light Corridor request, if required
  • Conducting pre-movement safety and compliance checks in line with permit requirements
  • Completing daily reports, vehicle logs and other administrative paperwork related to OSOM movements

Traffic Escort Warden Bookings

Traffic Escort booking forms have been replaced by our Traffic Escort Services Scheduling Solution (TESSS) portal. TESSS provides registered users the ability to undertake a range of traffic escort self service functions, including apply for, amending or cancelling traffic escort bookings (work orders).

We’ve created TESSS Frequently Asked Questions to assist in addressing questions you may have as a new user of TESSS.
